Title: Upgraded librets formula for the latest 1.5.3 version.

I upgraded the librets formula to use the latest librets-1.5.3 version.

I added a dependency on swig as OS X Lion doesn't have swig installed.

Snow Leopard may have had an old version of swig installed by default. I removed the hacks to support the old version.

I also removed the hack to support boost 1.46.0 as librets-1.5.3 already fixed this.
